摘要
Background Although the use of pure laparoscopic donor hepatectomy (PLDH) is increasingly common, it remains limited to a few experienced centers and no data on the learning curve are currently available. The aim of this study is to evaluate the learning curve associated with the use of pure laparoscopic donor right hepatectomy (PLDRH). Methods Data from donors undergoing PLDRH performed by a single surgeon between November 2015 and October 2017 were retrospectively reviewed. The learning curve was evaluated using the cumulative sum (CUSUM) method based on duration of surgery. Results Of 100 donors evaluated, none required transfusion or conversion to open hepatectomy and no irreversible disability or mortality was reported. The mean operative time was 320.7 +/- 51.8 min, and all grafts were successfully transplanted. The CUSUM analysis demonstrated a learning curve of approximately 60 cases of PLDRH. Estimated total liver volume > 1400 cm(3) and double portal vein orifices were seen to be risk factors for longer surgery time. Having adjusted for case mix with these factors, the risk-adjusted CUSUM analysis demonstrated a learning curve of 65-70 cases of PLDRH. Conclusions In conclusion, PLDRH is a feasible and safe procedure with a learning curve of 65-70 cases.
